MPC5746R
The MPC5746R is a high-performance 32-bit microcontroller from NXP Semiconductors, based on the Power Architecture core, designed for advanced automotive and industrial applications. It features a 160 MHz main clock frequency, enabling fast processing of complex control algorithms and real-time tasks. The device integrates a robust set of peripherals including multiple CAN, LIN, and FlexRay interfaces, making it ideal for vehicle communication systems such as engine control units (ECUs), transmission control, and chassis systems.
This microcontroller includes a dual-core architecture with a primary core running at up to 160 MHz and a secondary core that supports real-time operations or redundancy functions. The MPC5746R offers up to 1 MB of flash memory and 256 KB of RAM, ensuring ample space for firmware storage and efficient data handling. It also supports hardware-based ECC (Error Correction Code) for memory protection, enhancing system reliability in harsh environments.
Security is a key focus in the MPC5746R, featuring built-in cryptographic accelerators for AES, SHA-256, and RSA encryption, along with secure boot and code authentication mechanisms. These capabilities make it suitable for applications requiring compliance with automotive security standards like ISO 21434 and UNECE R155.
The device includes an integrated analog-to-digital converter (ADC) with high resolution and multiple channels, supporting sensor signal acquisition in motor control, battery management, and powertrain systems. Additionally, it features a high-resolution PWM module for precise motor control, essential in electric power steering (EPS) and electric vehicle (EV) applications.
Designed for robust operation, the MPC5746R operates across a wide temperature range (-40°C to +150°C) and meets AEC-Q100 Grade 1 qualification, ensuring reliability in demanding automotive conditions. Its low-power modes and dynamic voltage scaling support energy efficiency in battery-powered systems, while its fault-tolerant design includes watchdog timers, self-test routines, and error detection circuits.
The MPC5746R is supported by comprehensive development tools from NXP, including the S32 Design Studio IDE and evaluation kits, accelerating time-to-market for engineers. This makes it a preferred choice for developers targeting next-generation automotive systems requiring high performance, safety, and scalability.
